Warning over microwave mistake we're all making that could ruin your food

It’s the kitchenappliance most of us can’t live without - yet many of us are using it all wrong.

Whether it’s heating up last night’s leftovers or making a quick breakfast before work, the microwave is a hero for busy households. But according to Andrew Wright, founder of kitchen appliancebrand Cookology, simple mistakes could be ruining our meals and even damaging the appliance itself.

“Microwaves are brilliant tools when used properly, but we see the same mistakes again and again,” says Andrew. “People often treat them like a one-button solution, but a little know-how goes a long way in improving results and extending the life of the machine.” So, what are we all getting wrong?

Using unsafe containers

It’s commonly known that microwaving anything with metal – even foil trims or twist-ties can spark and damage the oven, but microwaving plastic can also be a problem. Plastic tubs that aren’t microwave-safe can leak chemicals into food, especially when heating fatty or oily dishes.

Forgetting to stir or rotate

Microwaves don’t heat food evenly, particularly in older models or versions without turntables. Stirring halfway through or rotating the dish ensures safer, more consistent results, especially important when reheating rice, meat or leftovers.

Sealing containers too tightly

Covering your food in the microwave is essential for even cooking and to avoid messy splatters, especially when heating items with high moisture or fat content. However, it's just as important to leave a small gap for steam to escape. Fully sealed lids can cause pressure to build up, which may lead to the container warping or the lid popping off.

Ignoring cleanliness

A dirty microwave absorbs more energy and cooks less efficiently. Food splatters also increase the risk of unpleasant smells and smoke. However, make sure to never clean your microwave with bleach or other ammonia-based cleaners.

In an enclosed space like your microwave, these can leave behind toxic fumes that can contaminate your food.

Using the top of your microwave as storage

If you’re in a smaller kitchen with limited surface space and a countertop microwave, it might be tempting to use the top of it for additional storage. However, this can block the vents, causing them to overheat, leading to potential damage or even creating a fire hazard.

Andrew’s top tips is simple - microwave-safe dishes, cover food loosely, stir halfway through, never heat food in airtight containers, and keep it clean.

“Microwaves can do far more than just reheat leftovers,” he adds. “With the right technique, they’re a powerful, energy-saving tool that can handle everything from steamed veg to mug cakes. We just need to treat them with the same attention we give to ovens or hobs.”
